Where to start with this one, Lucas is still in SM as a solo artist so he's not really blackballed. Some fans are weird about relationships and the rumors about him (which gaslighting and being a shitty bf isnt a crime} were disproven. Taeil on the other hand...we still dont know exactly what he did...but it was serious enough that SM kicked him out the group, it's ok to feel a certain way when his parts come on. Deja Vu does take some getting use to, and yes it slaps live (I guess its because the bass is boosted in the arena idk). Misfit track video wasn't the full song Jeno's 2nd verse is missing from it. Definitely check out WayV's discography Awaken The World or Phantom would be a good starting off point.
I don't think you noticed, but in From Home they sing in Korean, English, Chinese and Japanese. I really love this song especially for that. And it even has the 'thank you' in all the nationalities that NCT has.
It's not that he didn't want to return but he couldn't because the allegations and lies became so rampant that his reputation was ruined even if he didn't do all those things. He couldn't let that affect WayV and NCT as a whole.
you should react to "dip it low" by Lucas he's a solo artis now and also you check out WayV "Awaken the world" album I feel that would be a good introduction to their discography
